Extend a View, for example ImageView:

public class MyImageView extends ImageView{}

Override the onDraw()

@Override
public void onDraw(Canvas canvas){

    // draw the image you got from the camera
    canvas.drawBitmap(cameraImage, 0, 0, paint);

    // draw the date
    canvas.drawText("Date string", x, y, paint);

}

When you want to send the image:

myImageView.buildDrawingCache();
Bitmap bmp = myImageView.getDrawingCache();

For sending to the server, that's another question and many examples here on SO. Good luck.

Edit:

Bitmap photo = (Bitmap) data.getExtras().get("data"); 
//create bitmap with a canvas
Bitmap newPhoto = Bitmap.createBitmap(photo.getWidth(),photo.getHeight());
Canvas canvas = new Canvas(newPhoto);
canvas.drawBitmap(photo,0,0,null);
//draw the text
Paint paint = new Paint();
//paint.setColor(Color.BLACK);
canvas.drawText("write bla bla bla",x,y,paint);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
newPhoto.compress(Bitmap.CompressFormat.PNG, 100, stream);
//get bytes from stream and send to your server
